Female filter preference. (A) Mean relative time ± SEM spent by 12 females within the preference zones in front of males under the ultraviolet-blocking (UV-), short-wave-blocking (SW-), medium-wave-blocking (MW-) and long-wave-blocking (LW-) treatment filters during the 10 min test phase of the stimulus experiment. (B) Mean relative time ± SEM spent by eight females within the preference zones in front of empty tanks under the UV-, SW-, MW- and LW- treatment filters during the 10 min test phase of the control experiment.
